PATENT MECHANISM FOR DlscfHARclNG- COKE-OVENS.

SPECIFICATION forming part of Letters Patent N o. 731,912, dated June 23, 1903.

Application tiled April 28, 1903*. SerialNo. 154,700.

a citizen of the United States of America, residing 'at Switchback, in the county of Mc- Dowell, in the State of West Virginia, have invented certain new and useful Improvements in `Mechanism for Discharging Coke-Ovens, 3 of which the following is a specification.

`This invention relates to a machine for pulling coke from coke-ovens, and is particularly adapted for discharging beehive ovens. `In the manufacture of metallurgical coke `the oven known as the beehive oven, so `called because ,5

of its dome-shaped form, has been generally adopted, being found to give the best results. In the burning ofthe coal the coke is produced in the form of a caked massV having a vertical stratification, and it `is desirable to avoid as much as possible hori- 1 20 zontal breakage of the sticks and lumps extracted from the oven.

` p The object of this invention is to secure a quick and thorough discharge of the oven without unnecessary breakage of the coke.

` iton the instroke, .3o

\ The-invention consists principally in cokepuller comprising an underworking beveled scraper, which will slide along the bot# tom of acoke-oven and loosen the coke above and an overworking claw coperating with `said scraper to grasp and withdraw the loosened coke on the outstroke. Figure 1 represents a sideelevation of one embodiment of this coke-puller, a section of a portion of the coke-oven and of the receiv- `ing-car. scale,

This coke-pulling apparatus may be used for discharging various forms of coke-ovens.

The drawings represent fragments of a beehive coke-oven -10,* provided, as usual, with a top opening, which serves for a feed and blast opening, and with a lateral discharge opening l2. These openings are closed and sealed in the usual manner during the coking operation or a part thereof. A number of such coke-ovens are arranged side b v side, and a railway-track is disposed in front thereof, on which travel lthe coke-cars for receiving and conveying away the coke `from the oven. employed for disposing of the coke withdrawn `Any suitable means may be from the ovens. A track/ is disposed outside the track 20 parallel therewith, and a machine-car 50, on which the discharging apparatus is mounted, travels on said track 40. A suitable frame for supporting the mechanism of the cokepuller proper is mounted on the car 50. This frame may comprise two standards, as 51, secured to the platform of the car at opposite ends thereof connected by a top cross-bar 53aud intermediate cross-bars 54 and 55. The cross-bar 53 is provided with a vertical shaft-bearing 56, and the car-platform is provided in line therewith with a vertical shaft-bearing 57, having an exteriorange 58,adapted to serve as astepbearing. The platform of the machine-caris also provided with standards, as 60, on one side and with standards, as 62, on the other side thereof. These standards are connected on one side by two pairs of elongated antifriction-rollers 64 and 65 and 66 and 67, disposed one above the other in a horizontal plane mid` Way of the height of the main frame, and these rolls form guideways for the coke-puller, as hereinafter described. Corresponding rollers 64 and 65 and 66 and 67"'connect the standards at the other side of the car and form guides for said coke-puller.

A horizontal driving-shaft 70 is supported in bearings at the upper end of the frame and provided with a ily-wheel 72 and a beveled -pinion 73.

Any suitable engine or m otor and properly IOO ' The guideway 104 is may be employed for imparting motion to the driving-shaft, and this engine is provided with any suitable means usually employed for quickly starting, stopping, and reversing.

A vertical shaft 90 is disposed in the vertical bearings 56 and 57 and provided at its upper end with a beveled gear-wheel 91,which meshes with the beveled pinion 73 on the driving-shaft 70. This shaft is provided with a fixed pinion 92 and with a loose pinion 93, the hubs of which have clutch-faces. A sliding clutch 94, splined to the shaft, is adapted to engage the loose pinion 93 and lock it to the shaft, and a loose clutch 95 is adapted to engage the fixed pinion 92 and be turned thereby in unison with the shaft. These clutches are respectively actuated by clutch-levers 96 and 97. The clutch 95 is provided on the end opposite its clutch-face with a notch 98 for the purposehereinafterdescribed. Theshaft 90, which may extend through the platform, is shown as broken olf; but it may be connected by suitable clutch-gearing with one of the car-axles and utilized to drive the car along the track.

A swiveling carriage is mounted on the machine-oar for carrying the coke-puller, which is thrust into and retracted from the oven in the pulling of coke therefrom and moved laterally by means of the swiveling carriage to engage the coke at the side ofthe oven. This swiveling carriage may be of any suitable construction. As herein shownit comprises a sleeve 100, surrounding the vertical shaft 90 and resting on the step-bearing 58, being provided at its lower end with a worm-wheel 101. Abracket 102 extends upward from this sleeve and su pports two horizontal guide ways 103 and 104 at one side of the shaft. rlhe guide 103 is disposed opposite the loose pinion 93 and is open at the side adjacent to said pinion. The bott-om of these guideways may be provided with antifriction-rolls, as 105.

also open on its side adjacent to the shaft. A horizontal shaft 110 is journaled in bearings 111 and 112 on the car-body and provided with a worm 113, which engages the worin-wheel 101, and with a hand-crank 114, whereby t-he swiveling carriage may be turned to give a lateral thrust to the coke-puller.

Acoke-pullercomprising an under-working scraper and an overworking grappling-claw is mounted on and actuated from the swiveling carriage. The scraper is adapted to slide along the bottom of the oven underneath the bed of coke and is provided with means to lift and separate a portion thereof from the caked mass of coke within the oven on its instroke and to pull or` assist in pulling the so loosened coke out of the oven on its outstroke. This double-acting scraper, which. lifts and breaks the coke ou the instroke and pulls or scrapes it out on the outstroke, may be constructed in any suitable form which adapts it to its functions. The scraper shown in the drawings is attached to a sliding bar `140,

disposed in the lower guideway 103 of the swiveling carriage and passing between the rolls 64 and 65 on one side and between the rolls 64 and 65 on the other. This bar is provided along its rear portion with vertical rack-teeth 141, which engage the lower pinion 93 on the vertical shaft 90. The bar has a beveled outer end 142, which is provided on its under side with an antifriction-roller 143 to facilitate its movement on the ovenbottom. The scraper proper is composed of a tlat cross-plate 144, disposed at the outer end of said bar, and a bow-shaped plate 145, secured at its center to the beveled end 142 and at its ends to the ends of said cross-plate 144. The plate 145` thus forms a bevel or wedge inclined upward and backward from its outer edge. Both plates 144 and 145 are preferably arc-shaped at their outer edges to correspond With the shape of the oven, so that they may operate close to the wall thereof.

The overworking grappling-claw which operates in conjunction with the scraper comprises a bent shank 150, pivoted at its lower rear end to the bar 140 of the scraper, and a claw-head 151, secured to the outer end of said shank. -The claw is preferably a comblike or. toothed structure and shaped to conform to the scraper. Means are provided for raising the claw to escape the coke on the instroke of the coke-puller and to prepare it for grasping the coke at the completion of the instroke. The means shown for this purpose comprise a bar 160, disposed in the upper guideway 104 and between the rolls 60 and 67 and GG' and 67' and provided with vertical rack-teeth 161 along ils rear part. The outer end of this bar is connected to the shank 150 of the grappling-claw. Any suitable means are provided for operating this bar independently of the movement of the bar 140, and they preferably include devices for automatically determining the backward stroke of the bar 190, so that it will move just far IIO enough to properly raise or open the claw.

A bracket 104/ is mounted on the upper guideway 104, and a short vertical shaft 106 is supported in said guideway and bracket. This shaft has a loose pinion 107, which meshes with the vfixed pinion 92 on the vertical shaft 90, a fixed pinion 108, which meshes with the bar 160, and a splined clutch 109, adapted to engage said loose pinion for locking the shaft to move in unison therewith. A yoke 98', sliding in a slotted box 99 on the guideway 104, connects the loose clutch 95 on the shaft 90 with the splined clutch 109 on the shaft 10G. The lever 97 is pivoted on a lateral bracket 171 on said guideway and engages said yoke, whereby the latter may be lifted to throw the clutch 109 into engage-v ment with the pinion 107 to cause the rotation of the shaft 106 and the movement of the bar 160. A fixed tooth 172 on the guideway engages the notch 98 in the clutch 95 when the yoke is depressed, and a spring 173 operates to depress the yoke when the notch j ing ofthe claw. `The means shown for this `registers with the tooth.

claw connected therewith This will cause a forward thrust 'of the bar 140, and the coke-puller at the end thereof will enter the oven a distance sufficient to make a proper drawing of the coke. On this instroke of the coke-puller the beveled or Wedge-shaped scraper will lift and break or loosen from the `caked mass in the oven a body of coke equal in width to the width of the scraper andof a length equal to the length of the instroke. Several thrusts are to be at different angles in dis- During the instroke and after the claw 150 has passed the door-opening the hand-lever 97 is depressed by the operator and the clutches 95 and 109 placed in position to transmit motion from the :fixed pinion 92 on the vertical shaft 90` to the shaft 106, which 'carries the pinion 108, whereby the bar 160 is drawn backward and the grappling-claw 150 raised over the bed of coke andV automatically locked in open position and the clutch-gearing automatically disenbefore described or any equivalent means. When the coke-puller has entered the oven a distance sufticient to make a proper drawing of coke, the operator swings the lever 96, and thereby unclutches the driving-pinion 93, whereby theinward motion of the coke-puller is stopped.V The locking device for the grappling-clawis then released and the spring 163 operates to close f the'claw 150 in front of the loosened coke. The claw may be repeatedly opened and closed if found necessary to get a good hold on the coke. Then the operator will reverse the engine or otherwise cause the shaft 90 to rotate in the direction of the arrow b in lEig. 1 and again clutch the pinion 93 to said shaft.

This will cause a withdrawing from the oven" of the coke-puller, and the mass of loosened coke will be drawn through the door12 and allowed to fall into the coke-car 30. The claw 150 prevents any coke from falling back over the scraper and being left in the oven. After this stroke of the coke-puller another may be made in the same line, the puller being pushed farther into the oven, so as to take up` another load back to the 'opposite IOO IIO

Then the hand-wheel `114 will be successively manipulated toswing the swiveling frame into position to make lateral thrusts into the oven on opposite sides thereof, the several parts being manipulated, as

before described, to effect the coke-pulling stroke. The spring 163 may be omitted and the claw controlled by the operator, if desired.
